Freshman guard Austin Carroll, who is averaging 10.2 minutes per game, will miss four to six weeks with a left knee injury. He will have surgery Thursday.
It means the Scarlet Knights will be down to eight scholarship players for Wednesday's conference home opener against Marquette, which tips off at 7:3 p.m.
Senior forward Robert Lumpkins missed the last two games because of personal reason, but will dress and be available to play against Marquette as Rutgers (9-4, 0-1 Big East) looks to end a two-game losing streak.
Carroll is averaging 2.1 points and one rebound per game, and has 14 assists.
But his injury is more far reaching than tangible production. It means guard Mike Coburn and James Beatty, who are averaging 33.1 and 31.2 minutes per game, respectively, will be asked to play more minutes.
It also could mean more minutes for freshman guard Mike Poole, who is playing 19.7 minutes and 7.2 points per game.
